David from Graspable Math @david-landy.bsky.social · 01/09/2026I was worried about messing someone's bookmark in our shared audible for this book. I asked my sister, but mistyped. Her response? "I who have never listened to I who have never known men on an edible have never listened to I who have never known men on audible. Does that answer your question?" 000

David from Graspable Math @david-landy.bsky.social · 28/08/2026@enbrown.bsky.social I'm heading back to my family after a couple weeks away, and apparently it's not a moment too soon. I discovered today that they made an effigy of me for the dog...if you ask me, she mostly seems confused, and that seems like the right response. 000
David from Graspable Math @david-landy.bsky.social · 11/08/2026Graspable Math's game, From Here 2 There, got listed as 'Strong' in Evidence for ESSA! I remember drafting the first ideas for FH2T on our lab whiteboard back at the University of Richmond, with a team of truly amazing collaborators. www.evidenceforessa.org/program/gras... #MathEd #MathEdResearchevidenceforessa.orgGraspable Math: From Here to There (FH2T) - Evidence for ESSAGame-Based algebra skill development 001
David from Graspable Math @david-landy.bsky.social · 11/08/2026Obvious thought of the day: I'm working with our designer on a new set of classroom tools, and it's such a delight coding things in 2026: the new tools make it possible to rough things out so quickly and smoothly! 010
David from Graspable Math @david-landy.bsky.social · 09/08/2026So I really like industrial noise music, but I may have carried it too far. Yesterday I turned *OFF* the music I was listening to, because there was some electrical problem in the metro station, and it seemed like a really good song to me. I tried to record it, but the levels were weird. 010
David from Graspable Math @david-landy.bsky.social · 21/04/2026After a very long hiatus doing other projects, over the last two months I've been building new things in Graspable Math, and am having a lot of fun! I've been building what I'm calling 'Algebra manipulatives': little sandbox worlds that balance exploration and openness with constraints. More soon! 110
David from Graspable Math @david-landy.bsky.social · 19/06/2025This. So many people get upset about this, but getting mad at chatGPT for "lying" to you is quite •literally• like getting mad at a magic 8 ball for giving an answer to your question that looked plausible but turned out to be wrong. 010
